This system:– warns the driver that their vehicle is at risk of collision with the vehicle in front or a pedestrian.– reduces the vehicle's speed to avoid a collision or limit its severity.
This system is comprised of three functions:
– Collision Risk Alert.
– Intelligent emergency braking assistance.– Active Safety Brake (automatic emergency braking).

The vehicle has a camera located at the top of
the windscreen.
This system does not avoid the need for
vigilance on the part of the driver.
This system is designed to assist the driver
and improve road safety.
It is the driver's responsibility to continuously
monitor the state of the traffic, observing the
driving regulations.
As soon as the system detects a potential obstacle, it prepares the braking
circuit in case automatic braking is needed.
This may cause a slight noise and a slight
sensation of deceleration.
Deactivation / Activation
By default, the system is automatically activated
at every engine start-up.
The system can be deactivated or activated via
the vehicle settings menu.
Deactivation of the system is signalled by the illumination of this indicator lamp,
accompanied by the display of a message.
Without audio system
► In the "DRIVE ASSIST" menu on the
instrument panel display, activate/deactivate
"COLLISION ALT" (Automatic emergency
braking).
With audio system
► In the "Personalisation-
configuration " menu, activate/deactivate
"Auto. emergency braking".
With touch screen
► In the Driving / Vehicle menu, select
the "Vehicle settings" tab, then
"Security" and activate/deactivate " Automatic
emergency braking".
Operating conditions and
limits
ESC system in working order.
ASR system activated.
Seat belts fastened for all passengers.
Stabilised speed on unwinding roads.
In the following cases, deactivating the system
via the vehicle's configuration menu is advised:
– Towing a trailer.– Carrying long objects on roof bars.– Vehicles with snow chains fitted.– Before using an automatic car wash, with the engine running.– Before placing the vehicle on a rolling road in a workshop.– Towed vehicle, engine running.– When a "space-saver" type spare wheel is fitted (depending on version).– If the brake lamps are not working.– Following impact to the windscreen close to the detection camera.
It is possible that warnings are not given,
are given too late or seem unjustified.
The driver must always stay in control of the
vehicle and be prepared to react at any time
to avoid an accident.
After an impact, the function automatically stops operating. Contact a
CITROËN dealer or a qualified workshop to
have the system checked.

Driving
6Active Safety Brake

This function, also called automatic emergency
braking, intervenes following the alerts if the
driver does not react quickly enough and does
not operate the vehicle's brakes.
It aims to reduce the speed of impact or avoid a
collision where the driver fails to react.
Operation
The system operates under the following
conditions:
– The vehicle's speed does not exceed 37 mph (60 km/h) when a pedestrian is detected.
– The vehicle's speed does not exceed 50 mph (80 km/h) when a stationary vehicle is detected.
– The vehicle's speed is between 6 mph and 53 mph (10 km/h and 85 km/h) when a moving vehicle is detected.This warning lamp flashes (for approximately 10 seconds) as soon as
the function acts on the vehicle’s braking.
With an automatic gearbox, in the event of
automatic emergency braking until the vehicle
comes to a complete stop, keep the brake
pedal pressed down to prevent the vehicle from
starting off again.
With a manual gearbox, in the event of automatic
emergency braking until the vehicle comes to a
complete stop, the engine may stall.
The driver can maintain control of the vehicle at any time by sharply turning the
steering wheel and/or sharply pressing the
accelerator pedal.
Operation of the function may be felt by
slight vibration in the brake pedal.
If the vehicle comes to a complete stop, the
automatic braking is maintained for 1 to 2
seconds.
Malfunction
In the event of a fault with the system, you are alerted by the fixed illumination of this
warning lamp, accompanied by the display of a
message and an audible signal.
Contact a CITROËN dealer or a qualified
workshop to have the system checked.
Distraction detection
Refer to the General recommendations on the
use of driving and manoeuvring aids .
Take a break in case of feeling tired or at least
every 2 hours.
Depending on version, the function consists of
just the "Coffee Break Alert" system, or of this
combined with the "Driver Attention Warning"
system.
These systems are in no way designed to keep the driver awake or to prevent
the driver from falling asleep at the wheel.
It is the driver’s responsibility to stop if feeling
tired.
Activation/Deactivation
The system is activated or deactivated via the
vehicle configuration menu.
Without audio system
► In the "DRIVE ASSIST" menu on the
instrument panel display, activate/deactivate
"VIGILANCE ALT " (Fatigue Detection System).
With audio system
► In the "Personalisation-
configuration " menu, activate/deactivate
"Fatigue Detection System".

6Activating the function deactivates the Blind Spot Monitoring System.
You can deactivate the function at any time until the parking space entry or exit
manoeuvre begins, by pressing the arrow
located in the top left-hand corner of the
display page.
Selecting the type of manoeuvre

A manoeuvre selection page is displayed on the
touch screen: by default, the "Entry" page if the
vehicle has been running since the ignition was
switched on, otherwise, the "Exit" page.
► Select the type and side of the manoeuvre to activate the parking space search.
The selected manoeuvre can be changed at
any time, even while searching for an available
space.
Parking space search
► You should drive at a distance of between 0.50 m and 1.50 m from the row of parked vehicles, without ever exceeding 19 mph (30 km/h), until the system finds an available space.
The parking space search is suspended at
higher speeds. The function is automatically
deactivated if the vehicle speed exceeds 31 mph
(50 km/h).
For "parallel" parking, the space must
measure at least the length of your
vehicle plus 0.60 m.
For "bay" parking, the space must be at least
as wide as your vehicle plus 0.70 m.
If the parking sensors function has been
deactivated in the Driving/Vehicle touch
screen menu, it will be automatically
reactivated when the system is activated.


When the system finds an available space, " OK"
is displayed on the parking view, accompanied
by an audible signal.
Preparing for the manoeuvre
► Move very slowly until the request to stop the vehicle is displayed: " Stop the vehicle“,
accompanied by the “ STOP” sign and an audible
signal.
Once the vehicle has stopped, an instructions
page is displayed on the screen.
► To prepare for the manoeuvre, follow the instructions.
The start of the manoeuvre is indicated by the
"Manoeuvre under way" onscreen message
and an accompanying audible signal.
Reversing is indicated by this message:
“Release the steering wheel, reverse ”.
The Top Rear Vision and the parking sensors
are automatically activated to help you monitor
the area immediately surrounding your vehicle
during the manoeuvre.
During the manoeuvre
The system controls the vehicle’s steering. It gives instructions on the manoeuvring direction
when starting "parallel" entry and exit parking
manoeuvres, and for all "bay" entry manoeuvres.
These instructions are displayed as a symbol
accompanied by a message:
"Reverse".

Practical information
7Compatibility of fuels
Petrol fuels conforming to the EN228 standard
containing up to 5% and 10% ethanol
respectively.

Diesel fuels conforming to the EN590, EN16734
and EN16709 standards and containing up to
7%, 10%, 20% and 30% fatty acid methyl ester
respectively. The use of B20 or B30 fuels, even
occasionally, imposes special maintenance
conditions referred to as "Arduous conditions".

Paraffinic Diesel fuel conforming to the EN15940
standard.
The use of any other type of (bio) fuel (vegetable or animal oils, pure or diluted,
domestic fuel, etc.) is strictly prohibited (risk
of damage to the engine and fuel system).
The only fuel additives authorised for use are those that meet the B715001 (petrol)
or B715000 (Diesel) standards.
Diesel at low temperature
At temperatures below 0 °C (+32 °F), the formation of paraffins in summer-type Diesel fuels could prevent the engine from operating
correctly. In these temperature conditions, use
winter-type Diesel fuel and keep the fuel tank
more than 50 % full.At temperatures below -15 °C (+5 °F) to avoid problems starting, it is best to park the vehicle
under shelter (heated garage).
Travelling abroad
Certain fuels could damage your vehicle’s
engine.
In certain countries, the use of a particular
fuel may be required (specific octane rating,
specific trade name, etc.) to ensure correct
operation of the engine.
For all additional information, consult a dealer.
Refuelling
Fuel tank capacity: approximately 45 litres.
Reserve level: approximately 5 litres.
Low fuel level
/2
1 1When the low fuel level is reached, one of these warning lamps comes
on on the instrument panel, accompanied by an
onscreen message and an audible signal. When
it first comes on, about 5 litres of fuel remain.
Until sufficient fuel is added, this warning lamp
appears every time the ignition is switched on,
accompanied by an onscreen message and
an audible signal. When driving, this message
and audible signal are repeated with increasing
frequency as the fuel level drops towards 0.
You must refuel as soon as possible to avoid
running out of fuel.
For more information on Running out of fuel
(Diesel), refer to the corresponding section.
Stop & Start
Never refuel with the engine in STOP
mode; you must switch off the ignition.
Refuelling
Additions of fuel must be of at least 5 litres, in
order to be registered by the fuel gauge.
Opening the filler cap may create a noise caused
by an inrush of air. This vacuum is entirely
normal, resulting from the sealing of the fuel
system.
To refuel in complete safety:
► You must switch off the engine.

124
Practical information
► With the vehicle unlocked, press the rear-central part of the filler flap to open it.► Take care to select the pump that delivers the correct fuel type for the vehicle's engine (see a
reminder label on the inside of the filler flap).
► Turn the filler cap to the left.

► Remove the filler cap and hang it on its carrier (on the filler flap).► Introduce the filler nozzle and push it in as far as possible before starting to refuel (risk of
blowback).
► Fill the tank.Do not continue past the third cut-off of the
nozzle, as this may cause malfunctions.
► Refit the filler cap.► Turn it to the right.► Push the filler flap to close it.
If you have put in the wrong fuel for the
vehicle, you must have the fuel tank
drained and filled with the correct fuel before
starting the engine. The vehicle is fitted with a catalytic converter, a
device which helps to reduce the level of harmful
emissions in the exhaust gases.
For petrol engines, you must use unleaded
fuel.
The filler neck is narrower, admitting unleaded
petrol nozzles only.
Fuel cut-off
Your vehicle is equipped with a safety device
which cuts off the fuel supply in the event of a
collision.
Misfuel prevention (Diesel)
(Depending on country of sale.)
This mechanical device prevents filling the tank
of a Diesel vehicle with petrol.
Located in the filler neck, the misfuel prevention
device is visible when the filler cap is removed.
Operation

When a petrol filler nozzle is inserted into the
fuel filler neck of a Diesel vehicle, it comes into
contact with the flap. The system remains closed
and prevents filling.
Do not persist but introduce a Diesel type
filler nozzle.
It remains possible to use a fuel jerrycan
to fill the tank.
Travelling abroad
As Diesel fuel pump nozzles may be
different in other countries, the presence
of the misfuel prevention device may make
refuelling impossible.
Before travelling abroad, it is advisable to
check with a CITROËN dealer if the vehicle is
suitable for the distribution equipment of the
countries visited.
Snow chains
In wintry conditions, snow chains improve
traction as well as the behaviour of the vehicle
when braking.
The snow chains must be fitted only to the front wheels. They must never be
fitted to "space-saver" type spare wheels.
Take account of the legislation specific to each country on the use of snow chains
and the maximum authorised speed.
Use only the chains designed to be fitted to the type of wheel fitted to the vehicle:
Original tyre size Chain types
195/65 R15
Maximum 9 mm link
195/60 R16
205/60 R16 Cannot be fitted with
chains
215/50 R17
For more information on snow chains, contact a
CITROËN dealer or a qualified workshop.
Installation tips
► To fit the chains during a journey, stop the vehicle on a flat surface on the side of the road.► Apply the parking brake and position any wheel chocks under the wheels to prevent
movement of the vehicle.
► Fit the chains following the instructions provided by the manufacturer.► Move off gently and drive for a few moments, without exceeding 31 mph (50 km/h).► Stop the vehicle and check that the snow chains are correctly tightened.
It is strongly recommended that before
you leave, you practise fitting the snow
chains on a level and dry surface.
Avoid driving with snow chains on roads that have been cleared of snow to avoid
damaging the vehicle's tyres and the road

130
Practical information
► Remove the roof bars once they are no longer needed.
Maximum load, distributed over the roof
bars, for a loading height not exceeding
40 cm:
– without longitudinal bars: 50 kg,– with longitudinal bars: 45 kg.
As this value may change, please verify the
maximum load quoted on the note supplied
with the roof bars.
If the height exceeds 40 cm, adapt the
speed of the vehicle to the profile of the road
to avoid damaging the roof bars and the
mountings on the vehicle.
Be sure to refer to national legislation in order
to comply with the regulations for transporting
objects which are longer than the vehicle.
Bonnet
Stop & Start
Before doing anything under the bonnet,
you must switch off the ignition to avoid any
risk of injury resulting from an automatic
change to START mode.
The location of the interior bonnet release lever prevents the bonnet being
opened when the left-hand front door is
closed.
When the engine is hot, handle the
exterior safety catch and the bonnet stay
with care (risk of burns), using the protected
area.
When the bonnet is open, take care not to
damage the safety catch.
Do not open the bonnet under very windy
conditions.
Cooling of the engine when stopped
The engine cooling fan may start after
the engine has been switched off.
Take care with objects or clothing that
could be caught in the blades of the fan!
Opening


► Open the left-hand front door .
► Pull the interior release lever, located at the bottom of the door frame, towards you.

► Tilt the safety catch to the left and raise the bonnet.

► Unclip the stay from its housing and place it in the support slot to hold the bonnet open.
Closing
► Hold the bonnet and pull out the stay from the support slot.
► Clip the stay in its housing.► Lower the bonnet and release it near the end of its travel.► Pull on the bonnet to check that it is locked correctly.
Because of the presence of electrical
equipment under the bonnet, it is strongly
recommended that exposure to water (rain,
washing, etc.) be limited.
Engine compartment
The engine represented is an example given for
illustration purposes only.
The locations of the following elements may
vary:
– Air filter.– Engine oil dipstick.– Engine oil filler cap.– Priming pump.
* Depending on engine.

132
Practical information
Used products
Avoid prolonged contact of used oil or fluids with the skin.
Most of these fluids are harmful to health and
very corrosive.
Do not discard used oil or fluids into sewers or onto the ground.
Empty used oil into the containers reserved
for this purpose at a CITROËN dealer or a
qualified workshop.
Engine oil
The level is checked, with the engine having been switched off for at least 30
minutes and on level ground, either using the oil
level indicator in the instrument panel when the
ignition is switched on (for vehicles equipped
with an electric gauge), or using the dipstick.
It is normal to top up the oil level between two
services (or oil changes). It is recommended
that you check the level, and top up if necessary,
every 3,000 miles (5,000 km).
In order to maintain the reliability of the
engine and emissions control system,
never use additives in the engine oil.
Checking using the dipstick
For the location of the dipstick, please refer
to the illustration of the corresponding engine
compartment.
► Grasp the dipstick by its coloured grip and pull it out completely.► Wipe the end of the dipstick using a clean, lint-free cloth.

► Reinsert the dipstick and push fully down, then pull it out again to visually check the oil
level: the correct level is between marks A (max) and B (min).
Do not start the engine if the level is:
– above mark A: contact a CITROËN dealer or a
qualified workshop.
– below mark B: top up the engine oil
immediately.
Oil grade
Before topping up or changing the engine
oil, check that the oil is suitable for the engine
and complies with the recommendations in
the service schedule supplied with the vehicle
(or available from your CITROËN dealer and
qualified workshops).
Use of non-recommended oil may invalidate
the contractual warranty in the event of
engine failure.
Topping up the engine oil level
The location of the oil filler cap is shown in the
corresponding underbonnet layout view.
► Add oil in small quantities, avoiding any spills on engine components (risk of fire).► Wait a few minutes before checking the level again using the dipstick.► Add more oil if necessary .► After checking the level, carefully refit the oil filler cap and the dipstick in its tube.
During the 30 minutes after topping up
the oil, the check performed with the oil
level indicator in the instrument panel when
the ignition is switched on is not valid.
Brake fluid
The level of this fluid should be close to
the "MAX" mark. If not, check the brake
pad wear.
To know how often the brake fluid should be
replaced, refer to the manufacturer's servicing
schedule.
Clean the cap before removing it to refill.
Use only DOT4 brake fluid from a sealed
container.
Engine coolant
It is normal to top up this fluid between two services.
The check and top-up must only be done with
the engine cold.
A low level presents a risk of serious damage to
the engine.
The level of this fluid should be close to the
"MAX" mark but should never exceed it.
If the level is close to or below the " MIN” mark, it
is essential to top up.
When the engine is hot, the temperature of this
fluid is regulated by the fan.
As the cooling system is pressurised, wait at
least one hour after switching off the engine
before carrying out any work.
In order to avoid the risk of scalding if you need
to top up in an emergency, wrap a cloth around
the cap and unscrew the cap by two turns to
allow the pressure to drop.
Once the pressure has dropped, remove the cap
and top up to the required level.
Cooling of the engine when stopped
The engine cooling fan may start after
the engine has been switched off.
Take care with objects or clothing that
could be caught in the blades of the fan!
Screenwash fluid
Top up to the required level when necessary.

Fluid specification
The fluid must be topped up with a ready-to-use
mixture.
In winter (temperatures below zero), a liquid
containing an agent to prevent freezing must
be used which is appropriate for the prevailing
conditions, in order to protect the elements of the
system (pump, tank, ducts, jets, etc.).
Filling with pure water is prohibited under
all circumstances (risk of freezing,
limestone deposits, etc.).
Diesel fuel additive (Diesel
with particle filter)
On reaching the minimum level in the particle filter additive tank, this warning
lamp comes on fixed, accompanied by an
audible warning and a message warning that the
additive level is too low.
Topping up
This additive must be topped up without delay by
a CITROËN dealer or a qualified workshop.
AdBlue (BlueHDi)
An alert is triggered when the reserve level is
reached.
For more information on the AdBlue range
indicators, refer to the corresponding section.
To avoid the vehicle being immobilised in
accordance with regulations, you must top up the
AdBlue tank.
For more information on the Supply of AdBlue,
refer to the corresponding section.
Checks
Unless otherwise indicated, check these
components in accordance with the
manufacturer's service schedule and according
to your engine.
Otherwise, have them checked by a CITROËN
dealer or a qualified workshop.
Only use products recommended by
CITROËN or products of equivalent
quality and specification.
In order to optimise the operation of
components as important as those in the
braking system, CITROËN selects and offers
very specific products.
12 V battery
The battery does not require any maintenance.
However, check regularly that the terminals
are correctly tightened (versions without quick
release terminals) and that the connections are
clean.

134
Practical information
For more information on the precautions
to take before any work on the 12 V battery, refer to the corresponding section.
Versions equipped with Stop & Start are fitted with a 12 V lead-acid battery of specific technology and specification.
Its replacement should be carried out only by
a CITROËN dealer or a qualified workshop.
Passenger compartment
filter
Depending on the environment and the use of the vehicle (e.g. dusty atmosphere,
city driving), change it twice as often, if
necessary .
A clogged passenger compartment filter
can adversely affect air conditioning
system performance and generate
undesirable odours.
Air filter
Depending on the environment and the use of the vehicle (e.g. dusty atmosphere,
city driving), change it twice as often, if
necessary .
Oil filter
Change the oil filter each time the engine oil is changed.
Particle filter (Diesel)
When the particle filter is approaching saturation, this warning lamp comes on
temporarily, accompanied by a message warning
of the risk of filter clogging.
As soon as the traffic conditions permit,
regenerate the filter by driving at a speed of at
least 37 mph (60 km/h) until the warning lamp goes off.
If the warning lamp stays on, this
indicates a low Diesel additive level.
For more information on Checking levels,
refer to the corresponding section.
Following prolonged operation of the
vehicle at very low speed or at idle, you
may, in exceptional circumstances, notice the
emission of water vapour at the exhaust while
accelerating. This has no impact on the
vehicle’s behaviour or the environment.
New vehicle
During the first few particle filter
regeneration operations, you may notice a
"burning" smell. This is perfectly normal.
Manual gearbox
The gearbox does not require any maintenance (no oil change).
Automatic gearbox
The gearbox does not require any maintenance (no oil change).
Brake pads
Brake wear depends on the style of driving, particularly in the case of vehicles
used in town, over short distances. It may be
necessary to have the condition of the brakes
checked, even between vehicle services.
Unless there is a leak in the circuit, a drop in the
brake fluid level indicates that the brake pads
are worn.
After washing the vehicle, moisture, or in wintry conditions, ice can form on the
brake discs and pads: braking efficiency may
be reduced. Gently dab the brakes to dry and
defrost them.
Brake disc wear
For information on checking brake disc
wear, contact a CITROËN dealer or a
qualified workshop.
Manual parking brake
If you notice excessive brake lever travel or decreased effectiveness, the parking
brake must be adjusted, even between two
services.
This system must be checked by a CITROËN
dealer or a qualified workshop.
Wheels and tyres
The inflation pressure of all tyres, including the spare wheel, must be
checked on "cold” tyres.
The pressures indicated on the tyre pressure
label are valid for "cold" tyres. If you have driven
for more than 10 minutes or more than 6 miles
(10 kilometres) at over 31 mph (50 km/h), add 0.3 bar (30 kPa) to the values indicated on the
label.
Under-inflation increases fuel
consumption. Non-compliant tyre
pressure causes premature wear on tyres and
has an adverse effect on the vehicle's road
holding - risk of an accident!
Driving with worn or damaged tyres reduces the
braking and road holding performance of the
vehicle. It is recommended to regularly check the
condition of the tyres (tread and sidewalls) and
wheel rims as well as the presence of the valves.
When the wear indicators no longer appear set
back from the tread, the depth of the grooves is
less than 1.6 mm; it is imperative to replace the
tyres.
Using different size wheels and tyres from those
specified can affect the lifetime of tyres, wheel
rotation, ground clearance, the speedometer
reading and have an adverse effect on road
holding.
Fitting different tyres on the front and rear axles
can cause the ESC to mistime.

AdBlue® (BlueHDi)

To respect the environment and ensure
compliance with the Euro 6 standard, without
adversely affecting the performance or fuel
consumption of its Diesel engines, CITROËN
has taken the decision to equip its vehicles
with a system that associates SCR (Selective
Catalytic Reduction) with a Diesel Particle Filter
(DPF) for the treatment of exhaust gases.
SCR System
Using a liquid called AdBlue® that contains
urea, a catalytic converter turns up to 85% of
the nitrogen oxides (NOx) into nitrogen and
water, which are harmless to health and the
environment.
The AdBlue® is contained in a special
tank holding about 17 litres.
Its capacity allows a driving range of
approximately 5,600 miles (9,000 km), which
may vary considerably depending on your
driving style.
An alert system is triggered once the reserve
level is reached: it is then possible to drive for a
further 1,500 miles (2,400 km) before the tank is empty and the vehicle blocked.
If the estimated distance travelled by the vehicle
between two services is greater than 12,500
miles (20,000 km), it will be necessary to top up
the AdBlue.
For more information on the Warning
and indicator lamps and the associated
alerts, or the Indicators, please refer to the
corresponding sections.
Once the AdBlue® tank is empty, a
system required by legislation prevents
starting of the engine.
If the SCR system is faulty, the level of
emissions from the vehicle will no longer meet
the Euro 6 standard: the vehicle becomes
polluting.
In the event of a confirmed SCR system
malfunction, it is essential to visit a CITROËN
dealer or a qualified workshop. After 680
miles (1,100 km), a device is automatically
activated to prevent the engine from starting.
In both cases, a range indicator indicates
the distance that can be travelled before the
vehicle is stopped.
